LED buying guide A 10W LED can easily outshine a 12W competitor if it converts watts into lumens more efficiently. All the wattage tells you is how much power the bulb uses. The lumens tell you how much light the bulb puts out. The ratio between the two tells you how efficient the bulb is.

How long do LED lights really last? The first white LED light was put on the market in the mid-90s and since then vast improvements have been made to increase the original design’s efficiency and lifespan. While the average lifespan is 30,000 to 50,000 hours, you can find bulbs that last twice this long, up to 100,000 hours. This incredible technology continues to improve to provide homeowners with affordable, energy-efficient and long-lasting lighting.

LED lamp An LED lamp is an electric light or light bulb for use in lighting fixtures that produces light using light-emitting diodes. LED lamps have a lifespan and electrical efficiency which are several times greater than incandescent lamps, and are significantly more efficient than most fluorescent lamps, with some chips able to emit more than 300 lumens per watt. The LED lamp market is projected to grow by more than twelve-fold over the next decade, from $2 billion in the beginning of 2014 to $25 bill

Learn About LED Lighting LEDs are “directional” light sources, which means they emit light in a specific direction, unlike incandescent and compact fluorescent bulbs, which emit light and heat in all directions. For this reason, LED lighting is able to use light and energy more efficiently in many applications.

LED Traffic Signals: A Brighter Choice Changing bulbs less often saves on labor costs, as well. Red lights are on approximately 60 percent of the time or 5,300 hours per year, and use far more energy in a traffic signal than green or yellow lights. Often, they are larger with a higher wattage, as well. With the installation of LED traffic lights at 2,900 intersections, Chicago is saving $2.55 million in energy costs and $100,000 in materials, annually. 2  Carbon emissions have also been reduced by 23,000 tonnes.

How Blue LEDs Work, and Why They Deserve the Physics Nobel LEDs can now emit far more light using far less power than incandescent and fluorescent bulbs. For instance, an incandescent light bulb can emit about 16 lumens per watt of electrical power, and a fluorescent light manages about 70 lumens per watt.

How Much Light Do LED Bulbs Produce? Put another way, LEDs use about 12% of the energy used by halogen and filament bulbs to emit the same amount of light. We can also calculate that a 50 Watt halogen spotlight produces about 600 lumens. An LED light would need to be about 6 watt in power to produce the equivalent 600 lumens produced by a 50 watt halogen. We can now see clearly that a 3 watt LED spotlight would produce 300 lumens, not 600 lumens, so definitely not equivalent to a 50 watt halogen bulb.

Over illumination Lastly, the type of light bulbs that are installed has a significant effect on energy consumption. The efficiency of light sources vary greatly. Fluorescent lights produce several times as much light, for given power input, as incandescent lights do, and LEDs are continuing to improve beyond that.

Efficient energy use Sustainable transport. Efficient energy use, sometimes simply called energy efficiency, is the goal to reduce the amount of energy required to provide products and services. For example, insulating a home allows a building to use less heating and cooling energy to achieve and maintain a comfortable temperature. Installing fluorescent lights, LED lights or natural skylights reduces the amount of energy required to attain the same level of illumination compared with using traditional incandescent light bulbs.

Light Bulb Buying Guide Compact Fluorescent (CFL) and Light Emitting Diode (LED) bulbs are the most energy-efficient light bulb options. They have lower wattage than incandescent bulbs, but emit the same light output. This allows them to produce the same amount of light, but use less energy.View the chart for key differences.alogen bulbs use a filament that’s heated to the point of glowing, the same as incandescent bulbs, but they use less energy. 1  Halogen bulbs last on average 1 year. 2  Halogen bulbs do not contain mercury.

Do 'environmentally friendly' LED lights cause BLINDNESS? A study has discovered that exposure to LED lights can cause irreparable harm to the retina of the human eye. LED lights have been touted as a super-efficient alternative to traditional bulbs because they use up to 85 per cent less energy and each bulb can last up to 10 years. In April, Philips, the world's biggest lighting maker, reported a 38 per cent jump in LED light sales from last year.

Energy efficient lighting There are two main types of energy efficient light bulbs available in the UK. Compact Fluorescent Lamps (CFLs) and Light Emitting Diodes (LEDs). CFLs are a cost-effective option for most general lighting requirements. Replacing a traditional light bulb with a CFL of the same brightness will save you about £5 per year, or £70 over the lifetime of the bulb.

Are efficient LED bulbs worth the price? Keep in mind that LEDs are on a faster efficiency and price-improvement track than other lighting technologies. Some lighting industry executives expect the price for an 800-lumen LED bulb to fall to about $20 within two years, which changes the math significantly.

Energy saving light bulbs Only turn the lights on if you have to. Daylight is the most energy-efficient form of light. Turn off lights when you leave a room, unless you are going back within a few minutes. Choose low energy (compact fluorescent) lighting, there is a bulb available for virtually every situation and to suit all tastes.
